You clearly don't have a clue about art and graphic design.
Oh yes, i forgot that strange absolutely white cart, which is supposed to be metal and colored different in some palces, and wood things, which are supposed to be wooded, is nothing more or less then stylization, which makes the pictures symple and easy to take it out. No. I suggest to use color tool on all the models, ragdolls, it will stylize the picture a little more. Then we just take random brush, take white color, and randomly make the pic white, then say it is stylized and is the most stylish thing in that world and get artistic rates.
Oh yes, metal fences are the part of symbolism, They symbolise the level of technology in the future, which makes all the metal things be always white, shiny and clear, especially when there is a battle near. Also, weapons are not colored white because they are also symbolised, they show how are weapons bad and useless, so no one takes care about them and makes them white, clear and shiny. Plus, shiny and white dumpster symbolizes the care of the egology. In future people reuse everything and dumpsters should be clean, white, and (of coarse) shiny.
And that glow behind the trucks shows how people take care about the fresh air, so the atmosphere is in the best condition. The trucks look so bad because the rebels use them. Rebels and their stuff are shown being so bad because rebelling and negative emotions are bad, this picture shouldn't raise your negative emotions, so it teaches you that police is good, white, clear and shiny, and rebellish strangers with guns are bad. It also teaches you life, because the picture shows that police can't use good actions against the rebels and has to fight with them using their own methods, which tells you that defeating bad guys is only possible by using their methods, because htey won't listed to anything else.
The best pic ever xD.
